I'm almost finished with Robert Ludlum's novel THE ICARUS AGENDA, which has two slang phrases in it that have me scratching my head (a lot). "A two toilet Irish detective" is supposed to be American Boston-Irish slang, and I guess isn't too hard to figure out. I still wanna know!
Used as an exclamation at something happening. Eg. at a hurling match when a person scores a goal in a humurous way a person can joke.
"Did ya see that, Up she flew and the cock flattened her!"
